Title: The OPE meets semiclassics

Abstract: Most of the predictions of the large charge expansion concern the spectrum of the theory and the expectation value of light operators between two heavy charged states in CFTs with internal symmetries. In this talk I will show that also the correlation functions of three large charge operators with minimal scaling dimension can be computed semiclassically for arbitrary fixed values of the ratios of their charges. For a three dimensional CFTs with U(1) symmetry group, the result is obtained from the numerical solution of a nonlinear boundary value problem in the conformal superfluid effective field theory.
